DOOR.

Specification ol' Lettere Patent.

Patented March 23, 1909.

To all whom` it muy concern..

Be it known that l., Amman J. Firms., n, citizen of the United litntlfs, and rvffziflnt ol' Woodcli'll-on-lludeon, in the roiinty ol llud son and Stato of New Jen-:ty: have invented certain new and useful lniprovenients in Doors, of which the following is a .apecilicaf tion.

My invention ,relates to improvements in doors and [mrtieularly te that clase known as lire-proof doors usually constructed of metal.

In the present invention7 I have provided a door which is' made entirely of .sheet metal or of sheet material possefzsing the requisite durability and fire-prooi qualities.

Theubject ol my invention is to provide a door of this1 character whieh will hc simple in its construction., Vcoiop'aratively cheap to make, dispense Vwith all filling materials generally used in doers ol thiay ty `e, and present a door of highly linished eniljnttraotive appearanee. "2

A further object is to provide a door ol this character, having a glass panel whereby light may pass to o positc sides ol' the doorJ the surface edges o the panel molding mijn cent to the glaea, being iinished to promote the attractive appearance oi the door.

In the accom ianying drauing forming part of this cpecilieation, Figure i, is an elevational View ol' one forni of the ilnproved door. Fig. 2, aeentral vertical sectional View of the door illustrated in Fig. i. Fig. 3, is an 'enlarged vertical sectional. view of the` door minus .the panels below the glass, said section being broken toperinit the en-( 4larged illustration` Fig'. 4.'is a sectional de-' tail vieW'on the line 4*?4, Fig. 3. v

.The main or body portion of the door is constituted. by two sections .weh-nalily of sheet metal of the required tliickl'iess and L irensure by 'proper dies so as to assume the special form necessary for the puriwses in view. One

tion is A, and at the upper portion of both of the sections A and A the metal is removed to present a larve rectan ular opening suitable Vfor the application o. the glass panel redetails will beninore full dwelt upon shortly. In the operation of s apin the .sections A and A they may havewiuiy esired foutu-rea to lie ilus i or fonliguralion imparted thereto. 'lhus higra. l and 2 show the door sections so pursued that they present below the glass pai-nii opening, the pleased pamela l ll which cnil lnsui'iiouiided hy an ornamental n|olding li.

lhe metal at the edges ol the sections A and A is turned at right angles to constitute vertical end walls lfor the door, the turned parte@ of the section A at hoth edges of the door having ollset bendel e each of which receives the adjacent turn a ol the section A and thus provides e llush over-lapping joint externally at hoth door edges. The sections A and A through the medium of their turns and over-lapping portion are rigidly connected together by rivets a which are externally inserted through openings therefor in the over-lapping portions and upset and headed by means ofaheavy n'ietal hor which is introduced within the s ace between the .sections and held against the rivets to afford al proper abutment duringl the riveting operaiilOL'l.

As shown, the removal el the metal from the sections A and A for presentingY the glass panel opening results in 'flanges Az lor each section, which flanges extend inwardly with respect to the. :enel opening and are loeated nt the four sldee` of said opening. Miinifestly, the arrangement of llanges isduplicated and strictly correspoi'ids at all sides to the` panel opening. The door illustrated has: an ornate molding AS immediately contiguous to each flange. The character of such ornamentation, however, can be left entirely to fancy or-omitted altogether.

The s aces between the sections A and A,` below t e lower `panel B, between said lower panel and the u per panel B, and hetween 'the latter and t. 1e glass panel o ieinng, are spanned by stay boltsC, which while headed at one end are inserted through. openings therefor in one section of the 'door and bear within openings therefor in the opposite section of the door where thcy'are riveted. The metal of the sections A and A immediately surrounding each stay bolt perforation is inwardly u set to permit the ends of the bolt Il) with the exterior surfaces ol!I the door.

' vThe sections A and A are further eonnected and braced relative to each other at the bottom of thedoor 'bfv 'ametal reinforce D ronslsling ol a. shun. ol metal having; its side and i-nl edge portions` lient down at a right nn gleso thntsaid reinforce willsnuglyoccnpy the spare liotwron the sections .il and A itt tho llottoin portion ol Lliv door. The sido i-digo portions l; bol said reinforce l) nre (tonnel-.Inl to thil lower edge )ortions of the sections A and A'i This reinlorre, besides ronstitntinpr a further ronnertion and Iii-aco between the initio door sections as slated, also serves to i-,lose the space between said sections at the bottoni portion oll the door.

li) IC' designate Ushaped strips which are designed to servi: as retaining means for the glass enel. l`he bottoni strip IC is sup porter in positionby virtue of the laet that it ns over ends f which engage tho bottom llnn es A2 of the sections A. and A. The vertica side U-shaped retainin strips E have bends corresponding with tlgie bends c, and these are held engaged with the vertical side flanges A* of the main door sections and thus prevent said sections E from being laterally displaced in one direction or the other. A reinforce D', similar to the reinforce D, but in inverted relation relative to the latter, snugly occupills the space between the main door sections at the top part ofthe door and is riv cted to said section sides. The bottom of the-` reinforce D' has an opening therein extendin to the edUe portions d of said reinforce.

ownwardly inserted through the reinn force openin are two parallel plates Fl i which exten' the width of tno opening and depend down so that lower edge parts thereof can bebent to form overturns f embracing the upper transverse flanges A and thus re senting the top section o the glass pane retaining means. The upper edge ortions of the plates F are bent horizonte upon the bottom of the reinforce D so as to maintain such plates properly in position.

From the description thus for, it will be seen that a sheet metal door' of tire-proof qualities and highly attractive appearance is produced and of' comparatively sun :le construction and durable character. T e glass panel G is introduced into iosition hy simply ieing permitted to slide own the olenin presented at the top oi' thc plates F an` when said panel is at the limit of its descending movement it will be firmly retained by the U- 1haped strips at the bottom, and sides and the lower portions of the plates F at the to of the panel o inning,

lin the event of tlhc sections A., A", being absolutely imierl'orate when the door is in its completed -orin, which would be the rase if the glass panel opening was omitted, the liroproof qualities of the door would obviously e rrcntly augmented.

'lhe heads of the stay bolts (l. may be hrazed to the metal providing their counter sink bearings, and thus act to prevent the collapse of the side .wrtions A, A".

mense ln Fig. 3, the door structure is prartirullv the snow as that previously described, Init with the omission of the panels B l5.

llnvintr thus described my invention`- what l i-Iaini as new and desire to secure hy lic-.Ltors lntont, is Y l. il door comprising two side sections, swim-d together and both having metal re moved at their upper portions to pri-sent un opening for en indepeni' it ianel, the motnl o the side sections at the our sides of the panel Aopening,Y embodying inwardly projecting pairs of flanges, and U-shaped hearing sections engaging said [langes and having overlmnds to maintain them against dis-enga ement, and n panel bearing in and retained y said U--shapcd sections.

2, A doei' comprising two side sections scoured together and both having metal re moved at their lupper portions to present an opening for an 1n ependent panel, panel retaining means at the bottom and sides of said opening, the side sections embodying dependingr horizontal flanges at the top ofsaid panel opening, a reinforce within 'the top portion of the door and secured to the sido sections, the bottom of said reinforce containing an opening extending parallel with the width of the' door, plates depending down from said reinforce o cning and having!A overbends to embrace t 1o upper flanges of the panel o enng', the upper edge portions of seid p ates being turned upon the reinforce bottom, and a pane the top opening presented by the plates and adapted to descend, beer in and be retained by the overbend sections coperating with the opening flanges.
